5.0 System Operation This section will describe some of the basic system operating methods using your MMD Series test frame when used with either L2 or L3 Series software. For complete operating instructions, please refer to either the L2 or L3 Series User Guide. 5.1 Operating Principles MMD Series control is performed using L3 software and a computer workstation. The computer is an all-in-one, touchscreen computer that communicates to the MMD Series test frame using USB communications. Load measurements are performed by high accuracy Starrett load cell sensors per ASTM E4, ISO 7500-1 and EN 10002-2. Load measurements are conditioned by the MMD Series controller and displayed in various views for analysis. An internal, high resolution encoder is used to measure position and velocity. Two (2) extensometer ports let you connect extensometers for applications requiring more precise strain measurements per ASTM E83, ISO 9513 or EN 10002-4.
5.2 MMD and FMD Series Controls This section will describe the manual controls located on your MMD Series test frame.
5.2.1 Emergency Stop Switch The Emergency Stop Switch is located on the left-hand side of the MMD Series base. This switch interrupts power to the electrical drive system and brings the system to a stop as quickly as possible. WARNING Engaging the Emergency Stop Switch does not remove power to the system. When the Emergency Stop Switch is engaged, power to the drive system is interrupted. No crosshead movement is possible. When operated, the Emergency Stop Switch locks down into a closed position. The crosshead movement is disabled. To reset or disengage the Emergency Stop Switch, press down and turn counter-clockwise. The switch will release upwards and return power to the drive system.
